Causes of Explantation of Phakic Intraocular Lenses We read with interest the article by Alió et al.1 on phakic intraocular lens (PIOL) explantation in the January issue. There is an ongoing debate about the long-term safety of PIOLs, especially angle-supported lenses.2 In late 2014, Alcon Laboratories, Inc. discontinued production of the AcrySof CACHET Phakic Lens (Alcon Laboratories, Inc., Fo...

PURPOSE To evaluate efficacy, predictability, and stability of refractive treatments using light-adjustable intraocular lenses (IOLs). SETTING University Hospital Virgen de la Arrixaca, Murcia, Spain. DESIGN Prospective nonrandomized clinical trial. METHODS Eyes with a light-adjustable IOL (LAL) were treated with spatial intensity profiles to correct refractive errors. The effective chang...

PURPOSE To compare spherical aberration and contrast sensitivity function following implantation of four different foldable posterior chamber intraocular lenses (IOLs), namely Sensar, Akreos AO, Tecnis, and AcrySof IQ. METHODS In this randomized clinical trial, 68 eyes of 68 patients with senile cataracts underwent phacoemulsification and IOL implantation with Sensar (n=17), Akreos AO (n=17),...

An 80-year-old man had intraoperative loss of an intraocular lens (IOL) in the vitreous and simultaneous implantation of an anterior chamber lens. For the first 3 years his course was uncomplicated, but after this time he noted monocular double vision. The IOL in the vitreous had moved into the optic axis of the eye. The case presented here underlines the possibility of complications occurring ...

The standard intraocular lens (IOL) that is used to replace a cataractous lens cannot change focus from distant to near objects, so most patients need glasses for near vision after cataract surgery. Limited evidence suggests that accommodative IOLs provide better near vision than monofocal IOLs, but not better than multifocal IOLs. Long-term follow-up is needed to confirm patient outcomes, and ...

purpose: to compare the effect of implantation of a single-piece hydrophilic foldable acrylic intraocular lens (iol) with rectangular optic edge and a single-piece polymethyl methacrylate (pmma) iol with rounded optic edges on posterior capsular opacification )pco(. methods: this randomized clinical trial study comprised 74 eyes with senile cataract in an otherwise normal eye in patients older ...

Objective: To report opacification of hydrophilic acrylic and silicone foldable intraocular lenses (IOL). Designs: Case series. Participants: Five patients with IOL opacification. Results: We report five eyes of five patients with late opacification of the intraocular lens (IOL). Three patients had hydrophilic acrylic (SC60B-OUV-MDR, Inc), two had silicone IOL (Allergan SI30NB). Two out of the ...

In modern cataract surgery, spectacle freedom is becoming more and more important. Emmetropia can be achieved for patients with myopic or hyperopic refractive errors by selecting the appropriate spherical lens power. However, approximately 20% of patients who undergo cataract surgery have 1.25 diopters (D) of corneal astigmatism or more. (FerrerBlasco, Montes-Mico et al. 2009; Hoffmann and Hutz...

PURPOSE To evaluate the safety and efficacy of the iris claw phakic intraocular lens (Artisan; Ophtec BV, Groningen, The Netherlands) in patients with high myopia. METHODS Between May 1999 and July 2001, 93 Artisan phakic intraocular lenses (IOLs) were implanted in 60 patients affected by high myopia. All patients underwent 24-month follow-up. The power of the lenses ranged from -7.5 to -22.0...

The use of anterior chamber intraocular lenses (ACIOLs) in the 1970s produced a flood of late complications mainly from corneal decompensation and uveitis with secondary glaucoma plus hyphaema (UGH syndrome). This led to the development and widespread use of posterior chamber intraocular lenses (PCIOLs) and to ACIOLs receiving a bad reputation. The ACIOLs used were of a non-flexible closed loop...
